ABSTRACT:
An improved off-the-road pneumatic tire designed to be mounted on an associated design rim having a flange portion is described. The rim flange has an axially inward surface contacting the axially outward portion of the bead area of the tire. Each bead portion has a surface contacting a radially inner portion of the rim flange. The surface and the flange initially cease contact and diverge from one another at a location in the cross-section of the tire and rim and in a region of the flange in which a line L1 tangent to the flange surface and passing through the axis forms an angle greater than 0.degree. and less than or equal to 15.degree. with a radial line L2 passing through the point of divergence and perpendicular to the axis. The tire has a steel reinforced radial ply which extends between and wraps about each bead. The ply has an inflection point located radially between a radially outward surface of the bead and a radially outward surface of the rim flange portion.
